US Locksmith is a licensed (Lic #00443LK) locksmith company serving all of South Florida since 2004. Yes, a licensed locksmith can absolutely change a lock even when you do not have the original key. This is one of the most common services we perform, and it is faster and less expensive than most people expect.
How Does a Locksmith Change a Lock Without the Original Key?
A professional locksmith uses specialized tools to bypass or remove the existing lock without damaging the door. The most common method is picking the lock open, removing the cylinder, and either rekeying it with new pins or installing a completely new lock. In cases where the lock cannot be picked, such as high-security models, the locksmith may drill the cylinder as a last resort, then replace it with new hardware. Either way, you walk away with fresh keys and a fully functional lock.
What Are the Most Common Reasons for Changing a Lock Without a Key?
Three situations account for the vast majority of no-key lock changes in South Florida:
- Lost or stolen keys. When you cannot account for who has copies of your key, replacing or rekeying the lock eliminates the risk of unauthorized entry. This is especially common after purse or bag thefts
- Security upgrades: upgrading from a basic lock to a high-security deadbolt does not require the old key. The locksmith removes the existing hardware entirely and installs the new system
- Tenant or ownership changes. When someone moves out of a property, the safest practice is to change the locks immediately. Previous occupants may have made key copies that you do not know about
Will Changing a Lock Without a Key Damage My Door?
A skilled locksmith will not damage your door. Professional-grade bypass tools and techniques are designed specifically to open and remove locks without affecting the surrounding hardware, door finish, or frame. Drilling is a last resort reserved for locks that cannot be opened by other means, and even then, only the cylinder is drilled. The door itself is not affected. The new lock installs into the same mounting holes.
Proof of Ownership
A reputable locksmith will ask for proof that you own or are authorized to access the property before changing a lock. This protects both you and the locksmith. Have your ID and a utility bill, lease, or deed ready. This verification step is a sign that you are working with a legitimate, licensed professional.
How Long Does It Take and What Does It Cost?
Most no-key lock changes take 15 to 45 minutes per lock. The cost depends on whether you rekey or replace, the lock type, and whether it is during business hours or after hours. US Locksmith services across Miami-Dade, Broward, and Palm Beach County range from $39 to $499. A standard residential lock change without a key is typically on the lower end of that range.
